Graph cuts in computer visionAs applied in the field of computer vision, graph cut optimization can be employed to efficiently solve a wide variety of low-level computer vision problems (early vision), such as , the stereo correspondence problem, , object co-segmentation, and many other computer vision problems that can be formulated in terms of energy minimization. Many of these energy minimization problems can be approximated by solving a maximum flow problem in a graph (and thus, by the max-flow min-cut theorem, define a minimal cut of the graph).
Scale space implementationIn the areas of computer vision, and signal processing, the notion of scale-space representation is used for processing measurement data at multiple scales, and specifically enhance or suppress image features over different ranges of scale (see the article on scale space). A special type of scale-space representation is provided by the Gaussian scale space, where the image data in N dimensions is subjected to smoothing by Gaussian convolution.
Minor scaleIn music theory, the minor scale is three scale patterns – the natural minor scale (or Aeolian mode), the harmonic minor scale, and the melodic minor scale (ascending or descending) – mirroring the major scale, with its harmonic and melodic forms In each of these scales, the first, third, and fifth scale degrees form a minor triad (rather than a major triad, as in a major scale). In some contexts, minor scale is used to refer to any heptatonic scale with this property (see Related modes below).
ActionScriptActionScript est un langage de programmation utilisé au sein d'applications clientes (comme Adobe Flash et Adobe Flex) et serveur (Flash media server, JRun, Macromedia Generator), ou encore en tant que langage de script dans le moteur graphique Unity. ActionScript est un langage de script, orienté objet et prototype, fondé sur ECMAScript (conforme à 100 % avec la norme ECMA-262, révision 3, depuis ActionScript 3.0). ECMAScript étant une version standardisée de JavaScript, ActionScript et JavaScript partagent une syntaxe semblable.
Decomposition (computer science)Decomposition in computer science, also known as factoring, is breaking a complex problem or system into parts that are easier to conceive, understand, program, and maintain. There are different types of decomposition defined in computer sciences: In structured programming, algorithmic decomposition breaks a process down into well-defined steps. Structured analysis breaks down a software system from the system context level to system functions and data entities as described by Tom DeMarco.Tom DeMarco (1978).
Transformation de LegendreLa transformation de Legendre est une opération mathématique qui, schématiquement, transforme une fonction définie par sa valeur en un point en une fonction définie par sa tangente. Elle tire son nom du mathématicien Adrien-Marie Legendre. Les cas classiques d'utilisation de la transformation de Legendre se rencontrent en thermodynamique et en mécanique lagrangienne. En thermodynamique, elle permet de calculer le potentiel thermodynamique adapté à des conditions particulières.
